ABSTRACT:
A sectored antenna system has one or more dielectric lenses, each having a surface and two or more antenna feed devices tilted non-parallel to the lens surface and preferably angled in a V pattern. At least one of the feed devices radiate signals into said lens that emerge as separate directional beams, or the lenses receive incoming signals from different directions and focus them onto different antenna feed devices. The feed devices of the sectored antenna system have a dielectric constant of between about 5 and 15 and preferable about 10 and further has a mounting collar to mount the antenna feed devices about the lens to adjust for elevation, azimuth, radial and rotational orientation.
